### Cone Monotonicity: Structure Theorem, Properties, and Comparisons to Other Notions of Monotonicity

#### Abstract

In search of a meaningful 2-dimensional analog to monotonicity, we introduce two new definitions and give examples of and discuss the relationship between these definitions and others that we found in the literature.
